Well, you already noticed, yep, human versions of dearest lovebirds Simba and Nala, but it's more than that.
I've been playing Sims 4 and became obsseded with it. And I created a Simba and a Nala. xD
And for sure, they lived as happy couples who were crazily in love in the game. They had 3 kids, and both died old. <333 Simba was painter and Nala, a secret agent.
